Columbia County approves contested rezoning for quarry site with school‑hour truck restriction after lengthy public comment

The Columbia County Board of Commissioners approved a multi‑parcel rezoning on Jan. 6 to allow surface‑mining (quarry) operations on properties including Tax Map 040 Parcel 055B and several adjacent parcels, after residents and experts delivered extended public comment on health, traffic and groundwater risks.

Commissioner Malir introduced the rezoning motion (to convert split zones RA/M‑1 and RA to RA and S‑1, and to apply multiple planning conditions including traffic and paving improvements) and the board heard more than a dozen speakers before voting. Opponents said the quarry and nearby data‑center development should be considered together because they function as a single industrial corridor and can multiply local impacts. Gregory Guido told the commission the quarry “exists to support the data center,” saying the projects “function as one industrial system” and that treating them separately “hides the true cumulative impacts of this corridor.”

Residents and local health professionals detailed concerns about blasting, truck traffic, dust and groundwater. Dr. Morgan Groothan warned about fine particulate matter (PM10 and PM2.5) and cited peer‑reviewed studies she said link quarry emissions to respiratory problems in children. Multiple speakers noted proximity to several schools, including Baker Place Elementary, and warned that Lewisville Road and local bridges were not designed for heavy daily truck traffic.

Applicant representatives (Quality Materials / David Grayson) described planned mitigation: vegetated berms and buffers (company cited at least a 100‑foot buffer on much of the site and as much as 450 feet in other sections, plus a 750‑foot undisturbed area on the east), a reclamation bond, water‑suppression systems on conveyors and crushers, a fugitive‑dust control plan to be submitted to the Georgia Environmental Protection Division, and a commitment to pre‑blast surveys for homes within a stated radius. Grayson estimated quarry production at roughly 500,000 tons per year and truck traffic at about 100–125 in‑and‑out movements per day; he said blasting would likely occur once or twice per month and asserted that predicted vibration levels would be roughly 25% of state thresholds and that continuous monitoring would be provided.

Commissioners and residents pressed the applicant for specifics about advance notice of blasts, well testing and monitoring, enforceability of dust and traffic restrictions, and whether school‑period routes could be restricted. The applicant said dust and blasting are covered by state permitting (surface mine plan and air branch) and offered to fund turn‑lane improvements at its expense.

During debate the commission amended the rezoning conditions to add an enforceable restriction: no truck traffic making left turns onto Lewisville Road during school arrival and dismissal windows (the board discussed morning and afternoon windows approximated as 7:00–9:00 a.m. and 2:00–4:00 p.m.). The amended motion passed by voice vote; the chair announced it carried 3–2.

The vote authorizes the rezoning subject to the enumerated planning conditions (traffic improvements, platting and recording steps, surface‑mine plan submittals, and the school‑hour left‑turn prohibition). The amended condition is intended to reduce truck interactions with peak school traffic; commissioners discussed possible enforcement mechanisms and agreed to add the restriction as a condition of approval.

Next procedural steps noted during the meeting include required county and state permitting for the surface‑mine plan and submission of a fugitive‑dust plan to the Georgia Environmental Protection Division. Residents asked the county to pause and evaluate the quarry and data‑center projects together; commissioners did not adopt a pause at this meeting.

The board moved on to several other rezoning and land‑use items after the vote and adjourned later that night.
